To aZZ whom it may concern:

Be it known that I, EnAs'rUs E. WiINnLnY, a citizen of the United States, residing at L nn, in the county of Essex and State of assachusetts, have invented certain new and useful Improvements in Automatic Shoe-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

The invention relates to automatic or semi-automatic machines in which the requisite relative movements between the work and the means for operating thereon to bring them into proper relation at the point of operation are automatically controlled and eliected.

In various shoe machines it is necessary, in order to bring the operating Ineans and shoe into or to maintain them 1n proper relation at the operating point, to relatively tip them in one or in two directions. It is the primary object of the present invention to provide novel improved mechanism for accurately determining and effecting the relative tipping movements requisite for securing these results. To this end the invention contemplates determining the ti ping movements requisite for bringing te work and operating means into proper relation by feelers arranged to engage the surface of the shoe or other work adjacent to the point of operation, and connectedto control the action of the ti pin mechanisms. The preferred form o the invention is especially designed for use in a machine for lasting shoes, the parts of which have been assembled on a last, and in the drawings the invention is shown embodied in such a machine.

'In addition to the features outlined above,

the invention includes further features of construction and combinations of parts hereinafter described and set forth in ythe claims, the` advantages of which will be understood by those skilled in the art from' the following detailed description of the machine embodying the inventlon in its preferred form. i 4

The embodiment `ofthe invention illustrated in the drawings is provided with a stationaryllasting head of the consolidated hand method Aor migger head type, the general construction of which is fully described and illustrated inthe United States Patents to S. lV. Ladd and R. F. McFeely, 584544, June laici/7; sw; Ladd, 597,321, Jan. 11` 1898; and J. Cavanagh, Jr., 873,018, Dec. 10, 1907. The lasting head carries automatically operating pincers 1` a sole rest 2, a tacker 3, an edge guide 4, a plaiting mechanism actuating lever 5, and a wire reel springtension releasing rod 6. The lasting instrumentalities carried by the lastinghead are operated in the same manner as the corresponding lasting instrumentalities inthe patents referred to, and therefore, they need-notr be described in detail herein as reference may be had-to said patents. Certain improvements, however, have been made in the mechanism for actuating certain ofthe devices carried by the lasting head in adapting them to the operation of the present machine consisting princi ally in an improvement in the mechanism or operating the wire reel spring tension releasing rod 6 by which the rod is operated automatically to release the tension of the wire reel spring.

The plaiting mechanism actuating lever 5 is connected to one end of a horizontal rod 8 (Fi 3) ythe rear end of which is yoked to em race the free end of an arm 9projecting from the upper end of, a vertical rock shaft 1`0 journaled in lugs 11 projecting from the machine frame. The lower end of the rock shaft. 1'0 (Fig. 2) is connected to therear end of a horizontal rod 12, the forward end of which is connected to an arm projecting from a sleeve 13 rotatably mounted on a vertical pin -14 carried by a bracket luybolted to the machine frame. "The sleeve 13' carries a segmental?)a which meshes with a similar segment (Fig-1) formed on the knee lever 7.

The wire reel `spring tension releasing rod 6"(Fig, 3) is connected at its rear end to the lower end of a lever 16 centrally Vpivoted to oneof the lasting head su porting brackets.y The rupper end of the ever 16 is connected by a horizontal rod 17 to an arm 18 (Fig. 5) pivotally mounted on a rock shaft 19'ournaled in the machine frame. A secon arm 20 projecting from the rock shaft carries a roll 305 engaged by a peripheral groove formed in a cam 21 secured to the driving shaft 22 for the lasting instrumentalities.

The last having assembled thereon the insole and upper and parts within it, hereinafter for brevity termed the shoe, is mounted upon a jack 23 of the well known saddle and spindle type. This jack is cured to the upper end of a vertical spindle 24 (Figs. 1 and 17) which is splined in an elongated hub 25, mounted to rotate freely in a frame 26, but constrained from longitudinal movement therein by a pair of collars 27 secured to the hub. The frame 26 is pivota 1y mounted on a hollow vertical rod 28 carried by a second frame 29, the hubs of which are pivotally mounted on a vertical rod 3() which is pinned to a jack frame 31. Through the connections described the jack is rotatable and universally movable in a planete permit the operative to present different portions of the margin of the upper to the pincers. The jack is thrust yieldingly upward to maintain the insole in contact with the sole rest 2 by a spring 32 arranged within the hollow rod 28. One end of the spring is secured to an eye bolt 33 attached to a plug 34 fitted to the bottom of the hol- 100 low rod 28, and the other end of the spring is secured to, a horizontal pin 35 arranged to extend through opposed vertical slots 3G 1n the rod 28I and connected to a collar 37 slidably mounted on the rod. A flange on the collar 37 engages the forked end of a lever 3S centrally pivoted 0n a brace 39 on the frame 26. The other end of the lever is also forked to engage a flange formed on a collar 40 slidably mounted on the hub 25 and connected through a pin 41, arranged to slide through opposed vertical yslots 42 in the' hub, with the spindle 24. y

As is well known to those skilled in` the art, 4the pull of the pincers in stretching the upper over the last is called the updraw". `In practice, the best results are producedwhen the updraw 0f the pincers is perpendicular to the plane of the insole at the point of operation. In the operation of the commercial consolidated hand method lasting machine it is customary for the operative to ti'p the shoe longitudinally or laterally', or both*k longitudinally` and laterally to maintain the plane of the insole adjacent the portion of the margin ofthe upper being voperated upon by the lastinginstrumentalities substantially perpendicular to the lineoffpillloi the pincers in` theirnpdraw movement. To properly tip the shoe l the machine frame.

in the manner described requires considerable skill on the part of the operative. In the illustrated embodiment of the invention after the operative presents a pre-selected portion of the margin of the upper to the pincers the shoe is automatically tipped by rocking it to the right or left, that is, laterally, or tilting it to the front or rear, that is, longitudinally, as the occasion demands to bring the plane of the insole adjacent the pre-selected portion of the upper perpendicular to the updraw movement of the pincers. The operative is thus relieved of the duty of tipping the shoe.

To permlt the shoe to tip or tilt to the front or rear the jack frame 31 rises vertically from a carriage 43 (Figs. 1 and 17) which is provided with a series of rolls 44 to permit the carriage to slide on rails 45 formed in the opposite walls 46 and 47 of a supporting frame 48 (Figs. 1 to 4). The rails 45 extend in such an are that a movenient of the carriage 43 on the rails tilts the shoe mounted on the jack to the front or rear about the point of operation of the pincers. l

To permit the shoe to tip or rock to the right or left the opposite walls 46 and 47 of the supporting frame 48 have each two upper arms (Fig. 3) of channel form Fig. 5). The front arms of the walls 46 an 47 are connected by a hub 49 secured to the forward end of a rock shaft 50 journaled in The rear arms of the Walls 46 and 47 are also connected by a hub 51 secured near` the rear end of the rock shaft 50. The axis of this shaft asses through the point of operation of the pincers so that the shoe may be rocked to the right or left about the point of operation of the pineers by rocking the shaft 50.

In order to tilt the shoe automatically to the front or rear the carriage 43 is provided with a depending lug 52 (Fig. 1) to which is pivotally connected one end of alink 53 the other end of which is pivoted to an arm 54, in turn pivotally mounted on the supporting frame 48. Intermediate its ends the arm 54 isconnected by a link 55 (Fig. 3) to an arm 56 depending from a sleeve 57 (Fig. 5) mounted on a rod 58 carried by the arms 46 and 47. Projectingiupwardly from the sleeve 57 are two arms 59, each provided with rolls 60 which are engaged by a groove 61 (Figs. 3 and 5) lformed in acollar 62 loosely mounted on the rock shaft 50. The upper surface of the collar 62 is formed as a rack 63 which meshes with a segment 64 (Figs. 3 and 5) formed on an arm projecting from a rock shaft 65 Vjournaled in hubs 66 rising from` the machine frame. The segment 64 ispi'ovided with a pair of fianges 67 which embrace the rack 63 and thus prevent the collar 62 from rocking with the shaft 50.` The rock shaft 65 is provided at one end (Figs. 3 and 5) with a walking beam 68 the opposite ends of which are connected by a pair of rods 69 to a second walking beam 70 (Fig. 2) carried by a rock shaft 71, one end of which is journaled in a hub 72 formed in the machine frame (Fig. 4), and the other end of Which is journaled in a bracket 73 bolted to the frame. The rock shaft 71 carries a segment 74 which meshes With a segment 75 formed on a bell crank lever 76 pivoted on a horizontal rod 77 journaled in the machine frame.

The actuating mechanism for rocking the bell crank lever 76 to tilt the shoe to the front or rear of the machine through the connections described comprises a continuously rotating drum 78 (Figs. 1, 2, 4 and 6), the periphery of which is engaged by one or more rolls 79 (Figs. 2 and 26). The drinn 78 is keyed to a horizontal shaft 78a which is continuously rotated, during the operation of the machine, from the main driving shaft 79') provided with fast and loose pulleys 79, through the gears 7 9d. In the construction shovvn there are two rolls which are connected to operate in unison, a plurality of rolls being used to give additional power to the actuating mechanism. The rolls are supported in a carriage 80 (Figs. 2, 7 and 8) which is mounted so that it may move longitudinally of the drum 78 and the rolls are so mountedthat they may be turned to vary the angle of the rolls with relation to the direction of travel of the surface of the drum. So long as the axes of the rolls are parallel to the axis of the drum there will be no longitudinal movement of the carriage 80. If the rolls are turned in either direction so that their axes are at an angle to the axis of the drum then the rolls will tend to travel longitudinally of the drum and will move the carriage 8O in one direc tion or the other according to the direction in which the rolls are turned, and the rate of movement in either direction will depend upon the extent of the angular movement of the rolls. The travel of the rolls 'and carriage will cease as soon as the rolls are returned to a position in which their axes are parallel to the axis of the drum. To `permit the carriage 8O to move lon tudinally of the drum it is provided with an upper and lower series of sets of antifriction rolls 81, there being three rolls in each set (Figs. 2, 7 and 8). The upper sets of three rolls embrace a Han e 82 formed on an independent frame 83 bo ted to the machine frame. The lower sets of rolls embrace a flange 84 formed on the frame 83. The flanges 82 and 84 thus form rails for the carriage to slide upon. The sliding movement of the carriage is transmitted to the bell crank lever 76 to tilt the shoe to the front or rear according to the direction of movement of the carriage through the connections described by a rack 85 secured to a bracket formed on the carriage 80 and meshed With a se ment 86 formed on the vertical arm of the gell crank lever 76.

Referring now to Figs. 24, 25 and 26, each roll 79 is clamped between a air of lates 87 which are scoured to a sha t journa ed in boxes 88 slidably mounted in a roll carrier 89 which is supported by the carriage 80. Each box 88 is provided with a pin 90 which is surrounded by a coiled spring 91 arranged within a chamber 92 in the roll carrier and interposed between the box 88 and a spring retainer 93 carried on the end of a bolt 94 threaded in the'roll carrier. By manipulating the bolts 94 the pressure of the frictional engagement of the rolls 79 and drums 7 8 may be varied as desired. The roll carrier 89 is )inned to a shaft 95 Which is journaled in a bridge 96 formed on the carriage 80. The projecting end of the shaft 95 is pinned to a bell crank lever or tiller 97, the horizontal arm of which is provided at its free end with a roll 98. This roll engages a groove 99 formed in a cam plate 100 (Figs. 7 and 8), provided near its ends with bosses 101 which are secured to vertical rods 102 mounted to slide in bosses 103 formed on the frame 83. The vertical arms of the bell crank levers 97 are connected by a sectional rod 104, the sections being connectedby a turnbuckle 105. Through the connections described it Will be seen that `when the cam plate 100 is raised or lowered the shafts 95 are turned to vary the angle of the rolls with relation to the drum, and thus cause a longitudinal movement of the carriage 80. To prevent binding of the roll carriers as they are turned in t e carriage 80 each carrier is arranged to turn on a ball bearing 106 interposed between the carrier and the carriage.

The direction of the tilting movement of the shoe either to the front or rear and the extent thereof under the inluence of the actuating mechanism described is determined by a -feeler 107 arranged to engage the insole of the assembled shoe. This feeler is formed on the end of the horizontal arm of a bell crank lever 108 pivotally mounted upon a horizontal stud 109 carried by the lasting head. The vertical arm of the bell crank lever 108 is provided with a boss 110 which is connected to a boss 111 pinned to a shaft 112, journaled in'bearings formed in the lasting head, by a screw 113 threaded for adjustment respectively in pivot pins in the bosses. The shaft 112 carries a sheaye 114 which is connected by a screw 117 to the two runs 115 and 116 of a Wire arranged to Work iii' the sheave groove. The run 115 passes over an idler 118 carried by the taeker bracket on' thelasting head (Figs. 1 and 3), thenover an ldller 119 'carried by a bracket mountedon the machine' frame (Figs. 1, 3

and' 5), then under an idler 120 (Fig. 6) carried by a yoke supported by a bracket 121 bolted to a frame 83n similar to the frame 83. The lower end of the run 115 then passes to a sheave 122 journaled in the bracket 121. The lower ends of the runs 115 and 116 are connected to the sheavc 122 by a screw 123 (Fig. 11). From the sheave 122 the run 116 passes under an idler 124 (Fig. 6), over an idler 125 (Fig. 5), and over an idler similar to the idler 118 on the tacker bracket, back to the Sheave 114. The feeler 107 if; n0r mally pressed toward the insole by a spring 126 (Fig. 3 one end of which is connected to a pin 12 Secured to the machine frame, and the other end of which isy secured to a clamp 128 carried by the run 115.

The sheave 122 is connected, through a turn buckle rod 130, to a tiller 131 secured to a roll carrier 132 having a roll 133 arranged to engage the periphery of the continuously rotating drum 78. The roll carrier is supported in a carriage 134 mounted so that it may move longitudinally of the drum 78 upon horizontal rods 135 which are carried in a yoke 136 )rojecting from the bearings for the shaft 8l (Figs. 1 and 2).

The roll is so mounted that it may be turned to vary the angle of the roll with relation to the direction of travel of the surface of the drum. So'long' as the axis of the roll is parallel to the axis of the drum there Will be no longitudinal movement of the carriage 134. When the roll is turned in either direction so that itsaxis is at an angle to the axis of the drum, then the roll Will tend to travel longitudinally of the drum and Will move the carriage 134 in one direction 0r the other according to the direction in Which the roll is turned, and the rate of movement in either direction will depend upon the extent ofthe angular movement of the roll. The travel of the roll and carriage will cease as soon as the roll is returned to the position in which its axis is parallel to the axis of the drum. The carriage 134 is connected by links 137 and '1-38 (Figs. 7, 8 and 11) to vertical arms 139 and 140 respectively secured to the rear ends of rock-shafts 141 and 142 journaled in bearings ormediin the fra-me 83. The front ends 'of the rock shafts 141` and 142 are each connected by a horizontal arm 143 to a turnbuckle rod 144 connected in turn to a lug 145 formed on the cam plate 100.

When the shoe is properly located Afor the operation of the pincers the feeler 107 is 1n a Ineutral position, that is, a position in which thetiller 131 is `held at right anglesfto the axis "of the drum 78. Now then, when `the operative presents a pre-selected portion'of-the margin of the upperto the pincersdhe f eeler 107 is lowered by the spring'126'if` the insole adjacent the preselected margin oftheu'pper inclines down- Wardly and'tc thef'ront (Fig. 27). `This movement of the feeler rotates the Sheave 114 in the direction oi the arrow a (Fig. 27) and the sheave 122` in the direction of the arrow Z) (Fig. 11.). Rotation o1 the sheave .122 in the direction of the arrow b swings the tiller 131 in the direction o1 the arrow c (Fig. 11). The tiller thus turns the roll 133 so that its axis is at an angle to tlieaxis o1 the drum and the roll will travel longitudinally of the drum and will more the carriage 1311 on the rods 135 in the direction of the arrow d (Fig. 11). Longitudinal movement of the carriage 134 in the direction of the arrow d (Fig. 11)

raises the cani plate 100 and turns the rolls 79 to slide the carriages 80 to the right (Fig. 7) which is in a direction to tllt, through the connections described, the shoe to 'the `rear. The tilting of the shoe to the rear clvatcs the feeler 107 which, through the Wire over the sheaves 114 and 122, swings the tiller 131 in a direction opposite to that of the arrow c (Fi 11). The move mentoi the carriage 134 a so tends to swing the tiller in a direrlion opposite to the ar row f1 since sheave 122 holds the end of the tiller from movement With the carriage. The revers.l movement of the tiller,.under the, combined influence of the feeler as it is returned toits normal position, and of the relative travel of the carriage and end of the tiller causes the roll and carriage to retraverse the drum and return to their original or neutral position. This lowers the camv plate 100 to straighten tiller 97 and stopsthe longitudinal movement ot' the earriage and consequently the tilting of the shoe, as the feeler .comes into neutral position.

As the carriage 80 is not returned to the position from which it started like the rarriage 134, it iS desirable that accidental overruinlning of ,the carriage beyond the limitsof its travel be revented. To this end the'pposie ends o the cam plate 100 are provided with reversrly arranged olifsets 1,46 and147 `forming continuations of theeamwgroove 99. If lfor anyreason the tillei" 97 is l'not restored to a position Where the axes of the 'rolls 79 'are parallel to the axis ot ,thedrunn 7 8, when* the roll 98 reaches thefend A'of the groove`l99, the `roll 98 will be engaged by either the ol'set 146 or 147 und thi; tiller 97 will be turned to'bring the of the rolls 79 parallel to the axis of the drum 78. l

yIf he portion of the insole engaged by the feeer 'molines downwardly and to the rear then fthe' fefeler 107, through the connections described, swings the tiller 131in thedirection of thearrow c (Fig. 11). This causes thel carriage tovmove lon itudinally of the drum 78 and lower, throng the con.` nectionsidescrilieti,thn cam plate 10() to start the eatia'geniiving in 'a direction to artu'site the mechanism fortilting the shoe to the front` to bring the insole adjacent the presented ortion of the u per into a plane perpendicular to the updraw movement of the incers.

.Xs herein efore stated, the machine of (he drawings is provided with autonmtic mechanism for rocking thc shoe to the right or lrit to cooperate with the mechanism for tilting the shoe to the front or rear and thusl locate the insole adjacent the pre-sclectcd portion of the margin of the upper in :L plane perpendicular to the updraw moveu'ient of the pincers. The automatic mechanism for rocking the shoe to the right or left is controlled by a feeler 148 formed Von the end of a bell crank lever pivotally mounted upon the stud 109. The u per end of this bell crank lever is provided boss 149 which is adjustably connected to :1. sleeve 150 on the shaft. 112, by a threaded sri-ew 151. The sleeve 150 carries a sheave 152 to which is secured a wire 153. The two runs of this Wire pass over idlers similar to the idlrrs 118 on the tacker bracket. then over idlers 154 (Fig. 5), then under idlers 155 and 156 (Fig. 6), finally being secured by n screw 157 to a sheave 158 rotatably mounted in a bracket 121 on the frame 83a. The sheave 158 is connected by a turnbuckle rod `159 to a tiller 160 connected to a roll carrier 161 having a roll similar to the roll 133 engaged with the periphery of the continuously rotating drum 78. The roll carrier 161 is carried by a carringe 162 mounted to slide longitudinally of the drum 78 on the rods 135. The carriage 162 is connected by links 163 and 164 to vertical arms 165 and 166 (Figs. 9 and 10) respectively secured to the front ends of rock shafts 167 and 168 journaled in the frame 83a. Secured to the rear ends of each oi the rock shafts 167 and 168 is a horizontal arm 170 which is connected by a vertical turnburlrle rod 171 to a lug 172` formed on a vertically1 movable cam plate 173 similar in all respects to the cam plate 100.

When the operative' presents a 'prese'- lected portionof the mar 'n `e the u per vto the pincers in such positlon that the pane of the insole adjacent the pre-'Selected Ortion of the upper slants to the right or eft, thev feeler 148, through the wire l153 and connections described, either elevates or depresses the cam plate 173 depending whether 1t is necessary to tip the shoe to the right or left in order to bring the insole adjacent the pre-selectedportion of the upper 1n the proper working plane. The oove init'he cam plate 173 engages a roll 1 4.- on a tlller 175 arranged to operate two rolls 176 eni gaged wit the periphery;` of the continuouslyrotatingdrum 8,. vhe rolls are suported in a carriage 177 which is mounted delizie" in' the frame B3 longitudinally 0f with a the drum 78in thesamer napner that the carriage 80 slidesJ in the1igfme3. `When the cam plate 173 iselevated. the rolls are turned to move the carriage i177 in one direction and When the can'implate is-depressed the carriage 177 is moved inlythe other' direction. The carriage 177 Ycarries a rack 178 which is engaged by a segment 179 formed u on a bell crank lever180 (Fig. 4) pivot-- mounted on a stud 181 carried by a bracket 182 formed on the machine frame. The other end of the bell crank lever is formed as a segment183 which meshes with a segment 184 formed on a Walking beam 185I pivotally` mounted on a rod 186 carried by the bracket 182. The Walking beam 185 isconnected by a pair of rods 187 to a walking beam 188 keyed to the shaft 50. Through the connections described the shoe is automatically rocked to the right or left, the direction and extent of which is controlled by a mechanism operated by the feeler 148.

In order that the mechanisnrfor tiltingl the shoe and thus correcting its position may be retained in an inactive and neutral position between Successive operations of the shoe, mechanism is provided for nominally lockingthe correctin lmechanism in a, neutral position. This locA ing mechanism also serves to nominally retain the feelers in neutral `position4 and to prevent tipping of the shoe by the operator or otherwise in feedin or moving it between successive operations of the correcting mechanism. As shown in Figs. 11, 12 and 14, this lock comprises a band brake 189 mounted to inolose the periphery of each of the shea-ves 122 'and 158. The band brake is constructed in tivo pieces 190 and 191 hinged together at 192. The free ends of the pieces 190 and 191 are respectively formed as lugs 193 and 194 which support a boltv195. The pieces 190 and 191 y are normally held pressed against the ',sheave by a spring 196 coiled about the `shank of the bolt V195 and interposedbetween the lug 194 and aset of adjusting Vandlocking nuts 197. VVVit-h this construction the sheaves 122 and 158.are nominally locked by the brake bands. The hinged pieces of the brake band are separated to release .the sheaves through a horizontal `rock shaft 199 j'ournaled in the brackets 121 and 121u (Figs. l1 and 12), the opposite ends of Which are ,provided with Wedges 200 arranged to` enter between the lugs 193 and 194, and separate theA parts of the brakes against the tension` of the sp1-in s 196 (Fig. 14). ,This shaft 1,99 isl under vt e control of the operative. ,Tothis end one end `Aofthe, lsha-lt 199 is ,providedyvith an arm 201, which is connected to enlever-.202, pivoted on @bracket 203 `formed ,on the maclfiinefranie,` bya link 204, one'end of which is connectedtothearm20lhand the ,otherl 0f which `is connected to one end of the lever 202. The other end of the lever 202 is provided with a link 205, the lower end of which is connected to a floating rod 206 normally supported by a ledge formed on a link 207. The lower end of the link 207 is connected to the horizontal arm of a bell crank lever 208 (Fig. 2)y pivoted on the inachine fran'ie. The vertical arm of the bell crank lever is connected by a horizontal link 209 to an `arm 210 carried by a rock shaft 211 journaledin the machine frame. lntermediate its ends the rock shaft 211 is providedwitl'ra treadle lever 212 normally held in air inoperative position by a spring 213, one endiof Which is connected to the treadle and the other end of Which4 is connected-to the knee lever supporting bracket (Fig. 1). y After the operator places the shoe upon the jack the shoe is manipulated by rotating it or swinging it in a horizontal plane or by a combination of these movements until the insole adjacent to the portion of the upper desired to be operated upon is located at the Working point. During this manipulation by the operator the shoe is held against tipping movement by the tipping and controlling mechanisms which are locked in neutral position by the locking mechanism above described. To ermit the feelers to move` upward under tlie pressure of the shoe sole when it Iis in position against the sole rest 2, the run of Wire connected to the spring for each feeler is made in two sections joined by a yielding connection 198 (Figs. 1 and 3). This yielding connection enables the feelers te move upward from their neutral position even though the controlling mechanism with which they are connected is still locked. After the operator has positioned the shoe he deprcsses the treadle, thus releasing the controlling mechanism and feelcrs so that they may operate to correct the position of the shoe in accordance with the positions assumed by the feelers. As soon as the insole adjacent to the pre-selected portion of the upper is located iii a plane at ri ht angles to the updraiv movement of the pincers, the lasting instrumentalities are thrown into operation to last the preselected portion of the upper.

ln order to insure the proper positioning oiE the shoe before the lasting instrumentalities are thrown into operation, mechanism is provided, which for convenience ina-y be termed indicating mechanism, which is brought into apertain position when the con trolling mechanism is in neutral position` and which so controls the throwing into operation of the lasting instrumentalities, that these instrumentalities are notthrown into operation until the indicating mechanism is brought `into a position which indicates that the controlling mechanism has acted and has corrected the position of the shoe.

f ai. 225. (Fig. e).

As shown the indicating mechanism comprises horizontal arms 216l and 217 p1votcd on a vertical pin 218 carried in a bracket 219 and connected by links 214 and 21.5 to the carriages 134 and 162 respectively. Each of the arms 216 and 217 is provided with a slot 220. These slots register when the carriages are stationary which, as heretofore described, occurs when the feelers are in their neutral position. As soon as the registration of the slots indicates that the shoe is properly positioned, the lasting instrumcntalities are operated by mechanism now to be described, to last the pre-selected portion of the upper.

The lasting head driving shaft 22 is driven from the main driving shaft 7 9b by a sprocket chain 221 which passes over a sprocket 222 carried by a sleeve 223 on the shaft 22 and also over a sprocket 224 on the shaft 7 9". Normally the sleeve 223 rotates loosely on the shaft 22 but may be connected thereto to operate the lasting instrumentalities by a Horton clutch, indicated generally This clutch is provided with the usual dog 226 (Fig. 16) arranged to be engaged by a yielding trip 227 to separate the sleeve and the shaft. The trip is carried bv the vertical arm of a bell crank lever 228 pivoted on the machine frame. The horizont-al arm of the bell crank lever is connected to a vertical rod 229 slidably mounted in a guide lug 230 carried by the machine frame. The trip is normally held in position to engage the dog by a sprin 231 (Fig. 2) coiled around the rod 229 an interposed between a collar 232 secured to the rod and the lug 230, The lower end of the rod is slotted (Figs. 2 and 12) to loosely embrace a pin 233 carried on one end 0f an arm 234 secured at its other end to a rock shaft 235 (Figs. 2, 4 and 12) pivoted in brackets 236 formed on the machine frame.

In the illustrated embodiment of the invention the clutch is tripped to operate the lasting instrumentalities as soon as the slots 220 register. To this end the shaft 79 is provided with an eccentric 237 (Figs. 1 and 2) which oseillates, through the eccentric strap and link connection 238, a lever 239 pivoted on the machine frame. The lever 239 is connected through a link 239a toabell crank lever 240 pivoted on a bracket 241 on the machine frame. The vertical arm of the bell crank lever is formed with a segmental slot 242 which embraces a block 243 (Figs. 2 and 12). This block carries the rod 206 and is provided with a chamber 244 which receives a plunger 245 formed on one end of a rod 246, the other end of which is adjustably connected to a block 247 pivoted on an arm 248 depending from the rock shaft 235. @oiled around the rod 246 is a spring 249 interposed between the block 243 and a set of adjusting and locking nuts 250 connecting the rod 246 with the block 247. Through the connections described the block 243 is yieldingly connected to the rock shaft 235.

When the treadle 212 is elevated the block 243 is maintained in the bottom oi' the segmental slot 242 where it coincides with the pivotal movement of the bell crank lever 242, so that no movement is imparted to the rod 246. As soon, however, as the treadle is depressed, the block 243 is elevated in the slot 242 by the link 207 and rod 206 and consequently the rod 246 is reciprocated by the rocking of the bell crank lever 240. Reciproeation of the rod 246 rocks the shaft 235 and causes an arm 251 depending from one end of the rock shaft to move toward the slots 220 in the arms 216 and 217, It the shoe is being tipped, the lower end of the arm 251 stri les a ainst the rear ends of the arms 216 and 21%, the spring 249 at this time yielding t0 prevent breakage. If, however, the slots 220 register indicating that the shoe is properly located for the lasting operation the lower end of the arm 251 enters the slots 220. This movement rocks the shaft 235 which pulls down the rod 229 and trips the Horton clutch 225 to start the lasting instrumentalities.

In order to immediately relock the con-A trolling mechanism and to restore the trip 227 of the Horton clutch to a position where it may engage the dog 226 after one revolution of the shaft 22 and stop the lasting instrui'nentalities, the lower end of the arm 248 is connected to a link 252 which is connected in turn to the link 207 by a pin and slot connection 253. With the construction described, the link 207 is pulled from beneath the pin 206 which supports the block 243 by the link 252 when the shaft 235 is rocked, thereby permitting the block 243 to return to the bottoni oi" the slot 2412, the trip 227 to be restored to the influence of the spring 231, and the wed es 200 to be withdrawn to permit the ban brakes to lock the controlling mechanism in its neutral position. Then when the operative releases the treadle to the iniuence of its 'spring 213 the link 207 is reinserted beneath the pin 206 by a spring pressed pin 254 which is snppmted in a lug 255 on the machine frame and arranged to continuously engage the front edge of the link 207.

In order to prevent accidental displacement of the shoe ont of the position to which it has been placed by the operative in presenting the pre-selected portion of the upper to the pincers, the illustrated embodiment of the invention is provided with devices for locking the jack from rotation and also from free movement in a horizontal plane as soon as the shaft 22 commences to operate. Referring now to Figs. 17 to 23 inclusive, these devlces comprise a lock for prevent' i the pivotal movement of the frame 29, a loc 1 30
